mwilliams Thanks for explaing what caused the issue. However, if the right approach is:-
chown :grommunio /etc/grommunio-antispam/local.d/worker-controller.inc
then why is this not included in the post install processes within Grommunio-Setup.
As a non developer - I am lost as to what permissions should be where. Last night I looked on my live 2026.06.1 Appliance and found all the files in the /etc/grommunio-antispam/local.d/ directory are set as 644 for root:root. Replicating these security settings to my test 2026.06.2 instance fixed the issue, which I reported. If the permissions should be different then the setup program really should set them correctly during installation of Grommunio.
EDIT: Just rerun another test setup.
Firstly the new Boot Screen is a big improvement - looks much better now.
I can confirm the settings suggested above are applied by the new Grommunio-Setup, BUT the new grommunio-setup needs to have been aplied to the server before running the setup wizard. So during initial install run the update before running the setup wizard.
